No connections (because of proxy settings probably)

I just installed the beta but not a single website is displayed unfortunately, it seems that Vivaldi tries to connect by proxy (no idea why) so I looked at the network options in Vivaldi but just cannot find a simple "No proxy" there (only 2 vpn connections I have but do not use in this situation (and do not want to neither) I do not want to change my general internet settings of course so why is there no "No proxy" in the network settings ? No chance to go on any website with Vivaldi so far/without this

I should also mention that there are a number of different security programs that, since Vivaldi is too new to be whitelisted with them, and because Vivaldi is an "unfamiliar" program trying to access the internet, block it. I don't know if you use third party malware and antivirus programs, but if you do, that could be the source of your problem.
